On a 2018 Starlink system I went out this morning to refresh the radio after updating our Sirius subscription. I hopped in the passenger side so I didn’t have deal with seat adjustments, etc... Pushed the start button once for accy mode and performed the update. When I was done I pressed the start button twice to turn off the car. The radio continued to play. I opened the door, exited closed and locked the car from the passenger side. I could still hear the radio! I looked in and it was STILL on. I figured it would time out. About an hour later I went out still heard music and unlocked the car and opened the passenger door. Sure enough the radio was still on and playing. I walked around the car and opened the drivers door. The radio immediately turned off. Over the last 3 hours I played around with it and discovered the drivers door MUST be opened after turning off the the car or the radio will remain on indefinitely. I wonder what other systems do not turn off when working on the car and not exiting from the drivers side? After 4 hours of this I had to jump start the car to get it to actually start. I could definitely see how people are experincing dead batteries in brand new cars. I could see this as an issue while cleaning or vacuuming the interior and listening to tunes.
